A mysterious book borrower dropped off a library book checked out in the early 1970s. Why didn’t he or she pay for the tardiness? It was a special amnesty week for the library, where patrons could drop off overdue books, no questions asked.

The book in question: “Small Voices: A Grownup’s Treasury of Selections from the Diaries, Journals and Notebooks of Young Children,” a collection of diary entries by public figures written when they were children. (via AP)
